Acute appendicitis is the most common non-obstetric surgery pathology in pregnancy, its incidence can be varied and occurs at a higher rate during the first and second trimester of gestation. Its diagnosis is difficult and can be confused by the anatomical and physiological changes during pregnancy, which alter their clinical presentation. Common symptoms are abdominal located pain, vomiting and nausea. The diagnosis is mainly clinical, but laboratory tests and additional imaging help confirm or rule out this pathology, ultrasonography remains the most used imagiologic method. The most common complication of acute appendicitisduring the first trimester of pregnancy is spontaneous abortion, and in the second trimester premature delivery. Fetal mortality canoccur more frequently if there is a burst appendix, while maternal mortality has an incidence close to 0% in the studied cohorts. In the treatment laparoscopic surgery is recommended as it has fewer complications for both mother and fetus compared to laparotomy, although this statement requires epidemiological studies. It is important to consider the gestational age. Late pregnancy may limit the laparoscopic approach. Rev.cienc.biomed. 2012; 3 (1): 112-117
